Oparin-Haldane theory

Working independently, in the 1920s, Aleksandr Oparin and J. B. S. Haldane proposed similar theoretical
schemes for how life may have originated on Earth (see life,
origin). Hence, the term "Oparin-Haldane theory" is sometimes used when
referring to their views. The main similarities and differences between
Oparin's and Haldane's suggestions are summarized below. The first practical
test of the Oparin-Haldane Theory was the Miller-Urey
experiment, carried out in 1953.
